And Optimization techniques, having reached a degree of maturity over the past several years, are being used in a wide spectrum of industries, including aerospace, automotive, chemical, electrical, and manufacturing industries. With rapidly advancing computer technology, computers are becoming more powerful, and correspondingly, the size and the complexity of the problems being solved using Optimization techniques are also increasing. But Optimization techniques with analysis solver have many problems. For instance, the difficulties that a particular interface must be coded for each design problem and that the designer should be familiar with the optimization program as well as the analysis program. The purpose of this paper is Optimal Design Framework for Mechanical systems design. This Design Framework has two Optimizers, ADS (local optimizer) and RSM(Response Surface Method), and graphic user interfaces for formulation and optimum design problem and controlling the design process. Current Design Framework tested by two analysis solver, ADAMS and ANSYS. First this paper focused on the core Framework and their conception.

The purpose of this study is to understand the general process from textile design till fashion design and to understand the relation between the body structure by using the x-ray technique. The research method was to see background of the anatomic feature and human skeletal X-ray projection through historical aspect of publications, the Internet, and paper. In terms of production, in order to present a design that takes into account the unique silhouette of the human body without distorting the shape of the human skeleton, X-ray images that were reconstituted using a computer graphic tool (Photoshop CS) were reproduced into the fabric as intense images through the digital Textile Printing technique that is capable of expressing fine and delicate details, and applied into the design. An original design was developed that emphasized the impression of the human body being projected and the shape of the human skeleton realistically expressed in terms of silhouette and detail. The results are as follows: First, Body has a anatomic formative characteristic and its formativeness becomes as a great motive for the artistic expression and thereby it becomes more unique and available for new design expression. Second, Using the 'body frame' as the motive of the research, there's mainly tried to make an unique expression. Third, according to reconstructing human skeletal X-ray projection by using Adobe Photoshop CS2, it can be expressed strong and unique design. Forth, DTP which is being used as an essential technique, expresses the body frame realistically and being used the special type of functional product and silk. Likewise by discovering the diverse formativeness of our body frame and reflecting the sense of humanity into the pieces there's been able to make and develop an unique fashion design. I sincerely hope there is a hug progress in this research in this area.

Digital makeup(DM), depending upon computer graphic softwares, is applied to various fields, e.g. character works in movie and game industries and visual printouts in printing works. Focused on makeup field, DM is extremely conducive to developing, scientizing and informationalizing makeup patterns. Despite of unlimited potential of DM of which market size has been growing day by day, its practical use by domestic makeup experts and educators is much less active than expected as far, due to the lack of knowledge accumulation. The purpose of this study is to suggest some theoretical frameworks to generalize DM techniques and analyze two cases using the frames therefore support academicians' recent efforts to theorize DM techniques. The study 1) defines and categorizes the concepts of DM and DFX(digital special effect); 2) reviews the literature relevant to DM and generalizes the types and methods of DM techniques; 3) applies general frames to analyzing two movie cases, famous for their DM effects; 4) then suggests, based upon analytical results, some efficient ways for makeup experts to use DM techniques in practice. This study contributes to providing the theoretical grounds to conceptualize DM thus broadening makeup artists' interests in DM and awakening the scholarly concerns in cultural technology including DM.
